This is cool, and a great improvement over the previous generation Yamaha product. However, "Brass Resonance Modeling" may be confusing to some non-tech savvy consumers as it sounds similar to "physical modeling," a method of synthesis. The technology improvements are not synthesis, but rather a non-generative process more similar to a pair of noise-canceling headphones.
Can you cite any more specific info? I'm very curious. From the demos, the sound externally and direct is pretty much equivalent to the silent brass system I picked up in 1999, but without that huge bulb sticking out of the bell of course!
